I also have osteoporosis, but have decided not to take the biphos meds, or calcium. I have a genetic abnormality in terms of my body's ability to process calcium (kidneys calcifying, high blood and urine levels of calcium, kidney stones, demineralising bones) but even if I didnt I would be cautious about taking something that seems to worsen health statistics long term for women in terms of heart disease. sorry, cant remember paper, will try and find. I really think there is a powerful connection between metabolic downregulation/immune upregulation, endocrine disfunction, inc sex hormones, ME and osteoporosis. I hope diet and gentle exercise make a difference. I alo heard strontium helped, and magnesium, but I dont know the evidence. Its hard with very long term conditions to establish an evidence base that is truly looking at the condition over a lifetime, and research into a condition that primarily affects women in later life is not high on most peoples agendas. The pharma's are making a fortune from it, thats for sure.
